The article deals with Crystal Clear Technologies, a startup co-founded by Jim Harris and Lisa Farmen. The company is using nanotechnology to develop water filters that should sell at half the price of those made the conventional way. Crystal Clear's technology is based on organic molecules that bind to arsenic, lead and other metal ions that pollute drinking water. Known as bi-functional ligands, they should enable filters to trap up to eight times the metal of competing filters, which use reverse osmosis, according to Harris. Outdoor equipment maker Cascade Designs is working with the company to commercialize a portable purifier and a purification system for the U.S. Army and the Marine Corps.
